There are about a thousand uses for this thing and many security professionals use it all the time. Great tool and very useful for converting encodings/encryption, but there is so much more.
but here is a tool so that you never have to do that again as my apology for making you do it.įun fact, it is released by GCHQ, Britain's version of the NSA. It is annoying to do that by hand, but it does help in the long run.
png you downloaded using cp and name it "copyOfPng.png" However, we can use it to convert files into hex, make edits to them with our favorite text editors, then convert the files back into the correct formats.įirst, let's make a copy of the. Xxd is not really a hex-editor, it just displays hex. If you need to dig deeper than that, go to the RFC. It makes your brain hurt.Īny time you need to deal with a file format, google/wikipedia will provide most of the answers. You'll spend plenty of time looking through RFCs, but not right now. Nobody has this content memorized, but when they deep dive into a format or protocol, the RFC has the answers.

All files follow the rules for their file format. Shouldn't make much sense, but it should at least look cool.įile formats (and networking protocols, and all sorts of other things on the internet) are defined in documents known as RFCs. Open the file with xxd and check out what is in it.

If your job is going to require that, you can get good at it. All things considered, you can avoid binary and worrying about CPU stuff most of the time, so let's not focus on them too hard or be too freaked out it is really complicated. We've talked about enough hardware, but let's go back to the people side of computing.
